Parameters for ES930: Diagnosis Tab

In this tab you can enable diagnosis signals reporting the status, errors, etc., of the input channels. These signals can be measured like any other measurement variable.

As the information is intended for error analysis (if required), it might not be transferred in realtime, but measured in slow rasters.

The ES930 offers the following types of diagnosis signals:

• Diagnosis signals for digital input signals:
  The assignment of these diagnosis signals to the digital input channels is fix and can not be changed. The diagnosis signals are measured with the same rate (in the same raster) as the corresponding digital input channel.

  • Counter /active time counter / inactive time counter overflow: 32-bit counters which are independent of one another are the basis for both the counter function and time measuring. Every counter value corresponds to a time unit of 15 ns. A counter overflow happens when a counter reaches its maximum value. The counter continues to count.
  • Timeout: The Timeout function enables the signals at the input channels to be monitored. If there is no signal transition within the defined duration for the timeout, the (in-) active time provides the last measured value, and the corresponding diagnosis signal will get the value TRUE.

• Other diagnosis signals: The following diagnosis signals must be measured in the raster of another channel. This means that you must select the corresponding hardware channel in the Rate Group column; the raster assigned to that hardware channel is then displayed in the Rate column of the diagnosis signal.

  • Error state on power stage: The error state indicates errors in power stages. Two power stages are combined in a group. If there is a problem in a group (e.g. a short or an over voltage), the complete group is switched off to protect the power stages. A group always consists of a pair of channels.
    
  • Current overload on sensor supply: This signal indicates if there is an overload on a sensor supply voltage channel.
  • Error LED: Shows the state of the red error LED. For further information on the error LED, please see the ES930 User's Guide.
  • RP host overload: This signal indicates if there is a data overflow on the rapid prototyping module.
  • Open wire on thermo channel: This signal indicates if the thermocouple detects open wires (e.g. caused by a disconnected thermo element).
  • Min. pulse adaption on digital output channel: This signal reports if the minimum pulse length on the digital output channel was adapted by the ES930 in order to protect the power stage.

The following list shows the parameters in the Diagnosis tab of the ES930:

Diagnosis tab

No.

Shows a consecutive number for each entry in the hardware configuration table.

You cannot edit this field.

Sel.

Use this checkbox to enable or disable this signal for further configuration steps.

Disabled signals will not be available in the Experiment Environment.

You can also use the context menu commands Enable All Channels and Disable All Channels to enable or disable all channels at once that are displayed on the selected tab.

Name

Shows the name of the measurement variable assigned to this channel. The name can be edited. It must be unique for the whole configuration.

Units

Shows the unit of the signal to be measured.

The selected unit appears in the corresponding measure windows.

Rate Group

For diagnostic signals corresponding to digital input channels, this field displays the sampling rate of the corresponding digital input channel and cannot be changed.

For other diagnostic signals, the rate of one of the hardware input channels is used. By selecting one of the input channels in this field, the rate for that channel is displayed in the Rate field.

Note
If later on, the raster of a signal is changed in the Experiment Environment, the related diagnosis signal is also changed, and vice versa.

For digital input diagnosis, the diagnosis signals are measured together with the state of the corresponding digital input channel, i.e. the assignment is fix and can not be changed. The rate group can not be changed for these signals.

Rate

This field shows the default acquisition rate assigned to the hardware channel selected in the Rate Group column.

This is the default raster for the measurement of the diagnosis signal. The value can not be edited in this tab.

Comment

Enter any comment for that signal. The comment may be displayed along with the signal in some dialogs in the rapid prototyping or measurement and calibration tool used.

Note
You can only enter a comment for signals that are selected in the Sel. column.
